Renovation Quote: How to Read & Compare

To read a renovation quote in Singapore, check that every item is itemised with a clear scope, unit, quantity and unit price, then compare quotes only when they cover the same work. A trustworthy quote spells out materials, brands, dimensions, provisional sums and exclusions, so the bottom line reflects the real job rather than a headline figure. Never pick purely on total price; the cheapest quote is often the one that leaves the most out.

Most homeowners collect three to five quotes and find the totals hard to compare because each contractor lists the work differently. One may bundle carpentry into a single line while another breaks it into ten. This guide shows you how to line up quotes fairly, read what each item really means, and ask the right questions before you sign.

What should a proper renovation quote include?

A clear quote reads like a shopping list for your home. Each line should tell you what is being done, how much of it, what material or brand is used, and the price for that item. Vague one-liners like "carpentry works" or "electrical works" with a lump sum are a warning sign, because you cannot check what you are paying for.

• Itemised scope: each task listed separately with quantity, unit and unit price
• Materials and brands: laminate, quartz, tile grade, sanitary ware and switch brands named
• Dimensions: carpentry in running feet or per unit, flooring per square foot or square metre
• Provisional sums (PS): a budget placeholder for items not yet finalised, clearly labelled
• Exclusions: what is not covered, such as hacking, disposal, or appliances
• Payment schedule, GST treatment, timeline and warranty terms

How do I compare quotes fairly?

The most common mistake is comparing totals when the scopes differ. Put the quotes side by side and match them line by line for the same rooms and the same work. If one contractor includes hacking, tiling and disposal for the bathroom while another only tiles, their bathroom prices are not comparable until you add the missing items back.

Build a simple comparison table with one row per task, then note each contractor's price and what material they assumed. Gaps become obvious fast: a low total usually means fewer inclusions, cheaper materials, or work pushed into provisional sums you will pay for later.

What hidden costs should I watch for?

Extras that appear after signing are what blow budgets. Read the exclusions and provisional sums carefully, because that is where the real cost often hides. Ask the contractor to convert vague provisional sums into firm prices once you choose the actual material.

• Hacking and disposal of old fixtures, tiles or built-ins
• Debris removal and bulky waste charges
• Protection works, scaffolding, or working after HDB permitted hours
• Upgrades from base materials, such as thicker quartz or premium laminate
• Electrical or plumbing point relocation not counted in the base quote
• HDB or condo permit fees, MCST deposits and management approvals

Why are quotes so different in price?

Two quotes for the same flat can differ by thousands, and it is not always about margin. Material grade, carpentry method (carcass build quality, hinge and runner brands), the amount of custom work, and how much is subcontracted all move the number. A higher quote can be better value if it uses branded hardware and includes work the cheaper one excludes.

Be cautious with quotes that sit far below the rest. An unusually low figure often relies on thin provisional sums, basic materials, or a plan to charge variation orders during the job. Ask what assumptions drive the price rather than assuming everyone quoted the same standard.

How does GST and the payment schedule work?

Check whether prices are shown before or after GST, since a quote that looks cheaper may simply be excluding it. In Singapore only GST-registered contractors charge GST, so confirm the registration and make sure every quote is compared on the same basis.

A fair payment schedule is staggered against progress, for example a deposit, then payments tied to milestones such as hacking, carpentry install and handover. Avoid paying a very large sum upfront. Keep a final retention amount until the defects check is done and any snags are fixed.

Getting the renovation done right

Once you understand the quotes, the next step is choosing a contractor who scopes the work honestly and stands behind it. For a full home renovation covering hacking, masonry, carpentry, flooring, painting and the finishing trades, our renovation service can prepare a properly itemised quote so you know exactly what each line covers.

Because we also handle electrical and plumbing in-house, points, wiring and pipe works are quoted as real line items rather than vague provisional sums. That makes it far easier to compare our quote against others and to avoid surprise variation charges midway through the job.

Frequently asked questions

How many renovation quotes should I get in Singapore? Three to five is a sensible range. It gives you enough to spot outliers and understand the market rate for your scope, without dragging out the decision. Always ask each contractor to quote the same scope so the totals are comparable.

What is a provisional sum in a renovation quote? A provisional sum is a placeholder budget for an item that is not finalised yet, such as tiles you have not chosen. It is not a fixed price, so the final cost can go up or down once you pick the actual material. Ask to convert provisional sums into firm prices before signing where you can.

Is the cheapest renovation quote usually the best deal? Rarely. A low total often means fewer inclusions, thinner provisional sums, or cheaper materials, and the gap tends to reappear as variation orders during the job. Compare inclusions and material grade, not just the bottom line.

Should renovation quotes include GST? They should state it clearly. Only GST-registered contractors charge GST in Singapore, so confirm whether each quote is before or after GST and compare all quotes on the same basis to avoid a false saving.
